I don't know much about them, either. Apart from the absolute basics and what I've heard, of course. Their babies are supposed to be very difficult to get to eat. I'd personally like to try
B. irregularis at some point, though.
I think the point of getting venomous snakes, was that you would actually
have to try to avoid getting bit.
Otherwise, why not stick to hognoses and garters?
By this, I don't mean that you should, but rather that there are a lot of snakes that fit into that venomous-but-practically-harmless category.
